My rhodedendrum not looking good

Should I be worried?

 

Did it suffer in the dry weather, they tend to like damp soil and dappled shade especially when small.

 

That looks like wind or sun damage - or both.
If you can offer more info as to the aspect it's in and your general location and conditions, when you planted it, and what else is near it, that will help with advice @MrHappyDays.

 

Doesn't get much sun so that's okay. You might have hit the nail on head - I m not sure I watered enough in dry weather.

 

Not sun damage as its in shade part of garden; I have regularly fed throughout season; but think I may not have watered sufficiently in hot weather.

 

Why are you feeding it so much and what with? That could be the problem, along with lack of water, because they shouldn't need extra feed if the soil and conditions are right.
Some organic matter added to the surrounding soil and the odd mulch with bark or something similar is all the help they'd need.

 

Quite often I think too much emphasis is put on feeding plants, especially newly planted ones.
Without sufficient water the roots won't have spread as well as you need them to.

I'm a big believer in watering well in the first year, and unless the plants show real stress I try not to water in subsequent years.
Rarely feed anything that is planted out other than vegetables.

 

Yes - for shrubs/trees etc @pete, it's the soil that matters, so adding a bit of compost or similar now and again is the only feed they need.
I think you meant to say 'without' sufficient watering in your post, but watering is key - although I don't have to water much here with newly planted shrubs, but in a drier area, that's the important thing, especially if it's planted in summer.
Making sure the original planting prep is good is also important. The most important thing really, because if the soil isn't right to start with, it's hard to alter later on, and it might be too late by then. Compacted clay, or the opposite - light sandy soil, need a bit of help before planting anything to ensure a good result.

 

I'll edit it.

 

Aye- stop confusing me @pete. I have enough trouble confusing myself as it is
